Answer:

3.3atm is the new pressure of the container

Explanation:

In the car, the temperature of the container increases from 25°C  =298K to 55°C = 328K. To solve this question we must use the Boyle's law that state that the pressure of a gas is directly proportional to its absolute temperature under constant volume. The equation is:

P1T2 = P2T1

<em>Where P is pressure and T absolute temperature of 1, initial state of the gas and 2, final state.</em>

<em />

Replacing:

P1 = 3atm

T2 = 328K

P2 = ?

T1 = 298K

3atm*328K = P2*298K

P2 = 3.3atm is the new pressure of the container

Answer:

3.3 atm

Explanation:

First we <u>convert 25 °C and 55 °C to K</u>:

  • 25 °C + 273.16 = 298.16 K
  • 55 °C + 273.16 = 328.16 K

We can solve this problem by using Gay Lussac's law, which states that at constant volume:

  • T₁P₂=T₂P₁

Where in this case:

  • T₁ = 298.16 K
  • P₂ = ?
  • T₂ = 328.16 K
  • P₁ = 3 atm

We <u>input the data</u>:

  • 298.16 K * P₂ = 328.16 K * 3 atm

And <u>solve for P₂</u>:

  • P₂ = 3.3 atm

Using the trend for chlorine, create a rule for naming halogen oxyacids.
Vlada [557]
All oxayacids have cations so no need to name the cation (H+) If name of polyatomic anion ends in -ate change to -ic for acid and if it ends with -ite change to -ous for acid

Provide three different examples of how minerals can form on earth
Misha Larkins [42]
A mineral is a naturally occurring , solid, crystalline substance with a specific chemical composition. Minerals are usually inorganic and are formed by ionic, covalent or metallic bonding. Ionic bonds are the dominant type of bonds in mineral strictures. 90% of all minerals are ionic compounds. Minerals bonded by covalent bonds are strong, for example carbon bonded together to form diamond. Metallic bonds are a type of covalent bonds where the atoms have a strong tendency to lose electrons and pack together as cations.

The half life for the first order conversion of A to B is 56.6 hours. How long does it take for the concentration of A to decrea
sveta [45]

Answer:

It will take 188.06 hours for the concentration of A to decrease 10.0% of its original concentration.

Explanation:

A → B

Initial concentration of the reactant = x

Final concentration of reactant = 10% of x = 0.1 x

Time taken by the sample, t = ?

Formula used :

A=A_o\times e^{-\lambda t}\\\\\lambda =\frac{0.693}{t_{\frac{1}{2}}}

where,

A_o = initial concentration of reactant

A = concentration of reactant left after the time, (t)

t_{\frac{1}{2}} = half life of the first order conversion  = 56.6 hour

\lambda = rate constant

A=A_o\times e^{-(\frac{0.693}{t_{1/2}})\times t}

Now put all the given values in this formula, we get

0.1x=x\times e^{-(\frac{0.693}{56.6 hour})\times t}

t = 188.06 hour

It will take 188.06 hours for the concentration of A to decrease 10.0% of its original concentration.
